You have not catch.
You develop your SERVER-SIDE app/component using RB + V4RB Client.
Your app run on the server as second server.

    Vserver
    Your server process.

But your server process with help of V4RB_Client can connect to Vserver and
control it.

right

And btw, this is UNIX style. Each task is executed by small program.

RIGHT!!!

In this case YOUR application manage network protocol self.
And Vserver self do NOT act on the network.
It is hidden behind of your Server Application.
    
This is not trick!

I know that our friends in other team, use such way to wrap MS SQL.

I think you have found the right way -- you need to WRAP Vserver.

Look, such configuration opens to you even more cool ways!
For example your Server app runs on computer1.
It is connected to 5 other computers.
Each runs its own copy of Vserver.
And your app is connected to all 5.
And it can dispatch/distribute work between several Vservers!

Then you need to have

A) own notification system
2) do refresh each one second or less or more.
